OUAI Medium Hair Shampoo — Hydrating Sulfate-Free Shampoo for Color-Treated Medium Hair, Strengthens & Adds Shine (10 oz)

OUAI Medium Hair Shampoo is a hydrating, sulfate-free cleanser formulated to nourish medium-density and color-treated hair while reducing breakage and boosting shine.

This shampoo was created for hair that’s not fine but not super thick — the ‘‘in-between’’ textures that need moisturizing without weight. Its formula blends babassu and coconut oils, keratin, and kumquat extract to gently cleanse, detangle, and restore luster while remaining safe for color-, keratin- and chemical-treated strands. The scent leans fresh and bright, with Italian lemon, jasmine and soft white musk notes for an everyday fragrance lift.

How does this shampoo improve manageability and reduce breakage?

The blend of hydrating oils and protein helps smooth the hair cuticle and reinforce strands. Keratin adds slip for easier detangling, while coconut oil targets split ends and babassu oil replenishes moisture without heavy buildup.

• Keratin improves detangling and reduces friction during combing.
• Coconut oil helps seal and strengthen dry, damaged tips.
• Babassu oil hydrates scalp and strands for better flexibility.
• Formulated to cleanse without stripping natural oils, reducing brittle breakage.

Is OUAI Medium Shampoo safe for color-treated or chemically processed hair?

Yes — the shampoo is sulfate-free and formulated to be gentle on treated hair. It cleans effectively while protecting color vibrancy and preserving professional treatments like keratin smoothing.

• Sulfate-, paraben- and phthalate-free to limit harsh fading.
• Cruelty-free and gluten-free ingredients compatible with most color services.
• Designed to cleanse without over-drying processed hair.
• Works well alongside OUAI conditioners and treatments to extend results.

What hair types and concerns is this product best for?

This shampoo targets medium-density straight, wavy, curly or coily hair that feels dry, frizzy, or prone to breakage. It balances hydration and lightness so hair feels clean, soft and manageable rather than heavy or weighted down.

• Medium hair textures seeking moisture and frizz control.
• Color- or chemically-treated hair needing gentler cleansing.
• Hair with split ends or surface roughness that benefits from smoothing ingredients.
• Anyone wanting a fragranced shampoo with salon-style performance.

How should I use it for best results?

Apply to wet hair, massage into roots and work through to ends to distribute the formula and lift impurities. Rinse thoroughly and follow with OUAI Medium Conditioner; add OUAI Hair Oil to damp ends for extra shine and frizz control.

• Use a quarter-sized amount for medium-length hair, adjusting as needed.
• Focus on the scalp for cleansing, then glide to ends to condition and detangle.
• Pair with OUAI Medium Conditioner and OUAI Hair Oil for a full routine.
• Safe for daily use depending on personal cleansing needs.

Who is this for: OUAI Medium Hair Shampoo is ideal for people with medium-density hair—straight, wavy, curly or coily—seeking a hydrating, lightweight cleanse that protects color and reduces breakage. It suits anyone who wants salon-worthy softness and shine from a clean, cruelty-free formulation, and works especially well as part of a matched OUAI routine for frizz control and everyday manageability.
